To all whom it may concern:

Be it known that I, ZENA-s ALBERT CUR- TIS, a citizen of the United'States,.residing at Channing,

in the county of Hart-ly and State of Texas, have invented a new and useful Cushioned flire,` of which the following is a wheels,fand has for its object to provide for cushioning the same in a new and novel mant is furthermore designedto adapt the` tire for light lvehicles solas to efiectually cushion .the same, and also'to give the tire 4the necessary strength to sustain heavilyloaddvehicles and to maintain the desired .elasticity of the .tire under all conditions. Withthese and other objects-in view the present 'invention consists in the combination and arrangement of parts, as will be herein# after more vfully described, shown in the accompanying drawing, and particularly pointed out in the appended claims,

made within the4 scope of' the claims VVwithout departing from the spirit or sacriiicing any of thead- "vantagles of the invention.

In t e drawing, .Figure l is a side elevation of a portion ofa vehicle-wheel equipped with;

Fig. 1, showin 'plication to a tional perspective view on the line 4 4 of Fig. 3.

'the drawing. j The present tire includes tubular'ela's'tic 'sheath 1, formed of spring-4 plate metal, which is bent into substantially one embodiment ofthe present invention, parts being-broken away 'to show the inte- Fig. 2 is a sectional perspective view thereof.v Fig. 3 is a view similar to the invention adapted for ap- .-icyclewheel. Fig'. 4 is a sec- 'Snnilar numerals of reference designate corresponding parts in all of the figuresv of tub'ular form, the opposite edges of the plate being bent outwardly to form flat annular attaching-flanges 2. `T he vtread portion '3 of the sheath is somewhat thickened, so=as to withstand wear, andthe plate is also thickcned at the bends or folds 4, so as to prevent breaking of the sheath at this point., vBetween the parts 3l and 4- the opposite sides of the-sheath are relativelv thin the desired elasticity to the tire.

ner so asto -obviate the collapsing of the tire,

` as to vproperly it being under-v stood that changes in the form, proportion, size, and minor detailsm'ay be a substantially so as to give Patented march 1'2, 1907.

within ih/e 'sheath there is a helicalsprip 5, whichis of lessdiameterthan the sheat and lies snugly against the inner periphery thereof,4 whereby there is a considerable space between the outer periphery of the lspring and the tread of the sheath.` By this arrangement relatively light vehicles are sup'- porte'd by the sheath alonewhich has sufficientelasticity to properly cushion'thevehicle. Whenv the vehicle is loaded and traveling over rough roadways, the spring 5 comes int'o play when the tread of the `sheath `is compressed -suiiiciently v-to engage the spring, `whereby thespring 4prevents collapsing of the sheath and reinforces the same, s o cushion 'a heavily-weighted vehicle. f

When the present tire isapplied to. a wheel in the original 'construction' thereof, the fellyl 6 is provided at its outer peripheryA with opposite annular flanges 7, constituting a broad4 rim against which the iianges 2 of the sheath lie and are secured by means of suitable fas# 'tenings .8," preferably rivetspiercing the iianges2and7.l

'To adapt the invention to bicycle and' other wheels havingthe usual nconcav ed rim,

'asshown at'9'in Figs. 3 and 4 of the drawing a `wooden base 10 issecured tio the inner pe-` riphery of the tire, the inner edge of the basebeingl convexed 4so as to 1 snugly fit the conlcavity ofthe rim to which it 1s cemented or produce abroad oute'rface for the base, to w yond the adjacent end of theba'se is -constricted or reduced in diameter, as at 13,A

(shown in Fi .3,) so as to iit within the other vend of the s joint. That portion of the sheath "which, projects beyond one endof'the base 10 is slit eath, and thereby form-.a lap-"- along the bends 4, so as t0 receive the bends of l vthe opposite'- end permit the fla Ue'po-rtions of the projecti end of .the sheat to overlap the other ends o `the flanges, 'as shown at 2a, rivets14 being portion of the'sheath and 4 passed `through the overlapped flange por? vtions and the flange 1 1 of tle base- -.Tha t endof the tire which hasthe projecting base portion also has 'the helical spring projecting to the adjacent end of the base With its ex- `tremity extended, as at 15, and lying across the extremity of the base in a groove 16, the

extremity'pf the s ring being formed into a lateral prong 17, riven into the end of the base, s0,as to anchor the spring thereto. The -other end of the spring is similarly connected to the adjacent end of the base'by means of a complementary members upon the opposite -fends of the base, thereby tol prevent. lateral separation thereof.

Having thus described the invention, what is claimed is- 1. `A cushioned tire having outwardly-dif 4rected attaching-flanges, an annular base secured to the flanges, a coil-spring having angular ends embedded in the material of said annular base, and a metallic sheath hav` ing outwardly-directed vflanges secured to said annular lbase on opposite sides of said coil-spring.-

2.I4 A cushionedtire comprising a tubular sheath having one end reduced to Yfit Within 5 the other end, an annular base secured to the inner periphery of the sheath with the inner portion of the base convexed to fit the concavity of a wheel-rim, one end ofthe base being projected beyond the adjacent end of the sheath, and the other end of the base being tplrmilrliated short of the adjacent end of the s eat 3. A cushioned tire comprising a tubular sheath having one end reduced to-`it Within the other, an annular base secured to the 1nner periphery 4of the sheath with the innerl periphery'of the base shaped to it the rim of a Wheel, that end `ofthe base adjacent the reduced end of the sheath being terminated short of said end of the sheath, the other end of the base being projected beyond the adjacent end of the sheatl1 and\a helical vspring' contained Within the sheath with its ends connected to the respective ends ofthe base.

4. A cushioned tire comprising a tubular sheath having one end reduced'to fit Withiny the other end, a base secured to the inner periphery of the sheath and shaped to it the rim of a wheel, that end of the base which is adjacent'the reduced end of the sheath being terminated short of said end of the sheath,4 the rother end of the base being projected beyond the adjacent end of the sheath, and a helical spring housed within the sheath with its ends lying at the respective ends of thebase and formed into.y prongs driven into said ends of the-base.

In testimony that I claim the'oregoing asy my own I have hereto affixed my'signature in the presence-of` two witnesses."
